"I knew all about him from years back," said Solskjaer, who coached Daehli while in charge of United U21s. "I do not expect that Mats is a key player for us immediately, but we know that in a few years he'll be a hot name in Europe.

"Mats is down-to-earth and sensible, although there are big shoes to fill being called the biggest talent (in Norway).

"I'm quite sure he's going to play for a major European club in the future."

It's understood that United had a buy-back clause inserted in Daehli's deal should he fulfil his potential while under Solskjaer's guidance.
